Washington issued its first retail marijuana licenses on Monday with a middle-of-the-night email alerting bleary-eyed pot-shop proprietors that they’ll finally be able to open for business.

Randy Simmons, the state Liquor Control Board’s project manager for legal marijuana, said Sunday night that the first two dozen stores were being notified so early to give them an extra few hours to get cannabis on their shelves before they are allowed to open their doors at 8 a.m. Tuesday — an opening that’s expected to be accompanied by high prices, shortages and celebration.
